A drivetrain for connection between the output of a prime mover and a load is described herein. The drivetrain comprising a CVT including an input connected to the output of the prime mover and an output; a forward-reverse clutch assembly including first and second inputs and an output connectable to the load; the first input of the forward-reverse clutch assembly being connected to the output of the CVT through a CVT clutch. The drivetrain also includes an IVT gear assembly having a first input connected to the output of the prime mover, a second input connected to the output of the CVT and an output connected to the second input of the forward reverse clutch assembly through an IVT clutch; and an idler gear assembly interconnecting the first and second inputs of the forward-reverse clutch assembly.

Drivetrain configured for synchronous IVT to CVT transition

Clutch temperature management in a slip control method and arrangement for a drivetrain including a continuously variable transmission is described herein. The drivetrain includes a clutch that is so controlled as to slip when a torque higher than the usable torque attempts to pass through. The temperature data from the clutch is used to determine the usable torque. Accordingly, the clutch prevents the prime mover from stalling.

A continuously variable transmission (CVT) provided with an integrated gerotor pump that also acts as a rotation blocker is described herein. In one illustrated embodiment, the gerotor pump is used to pump lubrication and cooling fluid through a radiator and into the hollow shaft of the CVT.

A method where the spin factor is looked up in a table; the slip factor is measured and the clamping pressure is adjusted to achieve a slip/spin ratio provided in a desired range is described herein. According to another aspect, an active mechanical clamping mechanism using a longitudinally movable contact point is also described.

A multi-path liquid cooling arrangement for electric machines includes a heat storing element provided with channels having a generally C-shaped cross-section and cooling tubes so configured and sized as to be insertable in the channels is described herein. The cooling tubes, once inserted in the channels, are deformed to conform thereto, whereby heat stored in the heat storing element is extracted by circulating cooling fluid inside the cooling tubes.

The present invention is generally concerned with an inductance assembly that is so configured and sized as to be inserted inside the cooling assembly of an electric machine to thereby decrease the overall volume of the machine.

Inductance assembly for an electric machine

A cooling device for an internal stator of an electric machine. The stator includes a substantially cylindrical cavity having a substantially cylindrical internal surface. The cooling device includes a body defining an external substantially cylindrical contact surface. The cooling device further includes a biasing element connected to the body. The biasing element is so configured and sized as to bias the contact surface of the body against the internal surface of the rotor when the cooling device is positioned inside the cavity.
